I have just updated from 12.04 to 14.04 and now have difficulty setting up Apache 2.4 I am getting the following error:
Setting up apache2 (2.4.10-1+deb.sury.org~trusty+1) ... ERROR: Module mpm_prefork is enabled - cannot proceed due to conflicts. It needs to be disabled first! dpkg: error processing package apache2 (--configure): subprocess installed post-installation script returned error exit status 1 Errors were encountered while processing: apache2 E: Sub-process /usr/bin/dpkg returned an error code (1)
How can I disable the mpm_prefork so that Apache can continue?
